That is like saying the check engine light is caused by the gas cap and not to get the codes read. Let me say this again...

THE TRANS FAILSAFE IS JUST LIKE THE CHECK ENGINE LIGHT, YOU SHOULD GET IT DIAGNOSED PROPERLY. EACH CASE MAY BE DIFFERENT.

Some times it's the battery, sometimes it's the alternator, sometimes it's the torque converter, sometimes the harness/solenoids, sometimes the clutch packs slipping internally, sometimes the control module, sometimes a communication problem between the EGS and DME or between the EGS and DSC, etc. etc. etc.

Do the proper diagnosis and research to your problem on a case by case basis.

100%.

Its OK to share experiences of similar situations you've had regarding a problem, but you shouldn't follow it as the solution to your issue.

This stuff is hard )) Mine has the same problems, even alot more. I have a Thread about it. Today I was at the Motor specialist, he told me that it might be from the engine. It has some destabilization issues and he said that at least 2 cylinders are not working. Also he said that might be problems because my car was in the container for a month. So tomorrow i have to go to other specialist that deals with electronics. Also I plan getting battery charged or replaced. I'll see tomorrow
I had my car in alot of different places and all of them told me different things. So make sure you have a proper diagnoses first. Hope it's going to turn out little misunderstanding. Good Luck.

I've just had this Trans. Failsafe Prog. popped up on the cluster a few days now on my 2001 BMW X5 4.4i and I had the same problem two year ago and it got rid off by my neighbor who reset it with his GT1 and it worked fine until a few days ago, this Trans. Failsafe Prog popped up again. Does anybody live around Long Beach, CA have GT1? I really need some help to reset this light. Please help and I really appreciate before hand.

Hello
Does anyone know how to test alternator on 2001 BMW X5 4.4i whether it is bad. I used to test it on my Toyota's alternator by keeping engine running and removed battery cable, if engine stopped running that means alternator is not good. Can I do the same test on BMW X5? Please advise.
